SPRAY-VALVE.

Specification of To all whom it may concern:

Be it known that we, Annnirr B. Homo-1s and THOMAS M. DUGAN, both citizens of the United States, and residents of Mo Keesport, in the county of Allegheny and State of Pennsylvania, have invented. certain new and useful Improvements in Spray-Valves, of which the following is a specification.

his invention relates to valves, and the object of the invention is to provide an inr proved valve particularly applicable for use in ronnertion with wash basins, and to e1" feet a spray disrharge, whereby one may wash his hands in running water in a very convenient and satisfactory manner.

A further object of the invention is to provide for the opening and closing of the valve through the manipulation of a combined handle and dist-barge spout, the pre ferred embodiment of the spout being that of a rose or spray head.

With these and other objects in view, the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the drawings, and particularly set forth in the appended rlaims, it being understood that ehanges in the form, proportion, size and minor details may be made, within the scope of the rlaims, without (.leparti-ng from the spirit or sarritiring any of the advantages oithe invention.

Tn the drawings,

Figure l is a perspective view showing the valve of the present invention employed in ronjunotion with a wash basin.

Fig. 2 is an enlarged longitluliual sew tional view embodying the features of the present invention.

Referring, first. more partirularly to Fig. 2 of the drawings. it. will be soon that the present invention includes a easing I, Wlli('ll. in the present embodiment. is in the form of u rvlinder whirh is open from end to end. ()ne end of this eylindriral rasing is pro vided with a coupling designated 2, which, in the present embodiment of the inven: tion, is in the form of an enlarged head or external flange provided with interior screw threads 3. whereby the easing may be connected to a. pipe or other suitable nrce of supply. Tn the present instance, he coupling is a rigid or integral part of the casing. Furthermore, the coupling is Letters Patent.

disposed obliquely across the end of the casing. in order that the latter may have the desired downward inclination when mounted above a wash basin, but it is, of rourse, tll llli'll'tllt that the roupling might be ronr-entrir instead of ecrcntrir, acrording to the desired disposition of the casing with respert to the support to which it is applied.

The outer or forward end ot the raising is externally threaded. as at l. and the same end of the raising is provided with interior threads 5 whirh are coarse or of great pltt-h for a purpose as will he hereinafter do srribod. At an intermmliate point. the valve rasing is provided with a transverse parti tion (I pierred bv a central opening T. An outstanding rylindriral flange t surrounds the opening 7 and constitutes a valve seat.

Extending longitiulinally through the outer end of the easing is a tubular valve stem 9 having its intermediate portion extending through a gland or stufllng box 10 provided upon the outer end of the valve rasing and engaging the external threads 4 thereof. This stem. is provided at its inner end with an enlarged circular head 11. pro vidrd on its periphery with coarse threads fitting the threaded portion 5 of the valve 'r-asing. so that a relatively great cndwise movement of the valve stem may be ob luined by a slight rotation thereof. A valve disk 12 in the form of a rubber, leather or other dish washer is serurcd to the inner end of the valve stem in any suitable manner. say for instance, by means of a screw 13 passing through the middle of the valve .und engaging a threaded opening in the end of the stem. Branch passages 14 extend diagonnllv outward from the longitudinal passa e in the valve stem and open out- \\'ardl v through the periphery of the head between the valve 12 and the threaded part of the head. The head of the valve stem. at the inner side of the threaded portion there o l. is somewhat reduced so as to provide an annular spare between the head and the walls of the casing. At the outer end of the valve stem there are diagonal or oblique 'iassages l5 communicating with the (en tral passage and opening through the periphery of the valve stem. A regulating screw 16 extends into a threaded opening in the outer end of the valve stem and may be moved into and. out of the outer end of the longitudinal passage of the stem so as to eontrol the hranrh passages 15 and regulate the passage of water therethrough.

roinhined handle and spray head 1? is provided upon the outer end of the stern. 'lhis spray head is hollow and round or substantially spherical in shape. The hark wall thereof is provided with a threaded opening 18 rereiving the external threaded portion of the forward end of the stem, which latter projects into the interior of the head. The front wall oi the head is provided with perforations ill for the pas sage of water therethrough.

In using the valve, the ((Illllllllltl spray head and handle is grasped in the hand and turned to the left, thereby moving the valve disk 12 away from its seat and permitting the water to flow around the inner end of the valve stem, through the lHHII lI passages l-l, thenre along the ventral passage. then out through the outer liranrh passages to into the head. and linally esrapiug through the perforations if) in the ltll'lll of a spray or shower; wherehy one may very eon veniently wash his hands in the running." water issuing from the spray in *ad. After the hands have heen washed and also rinsed hy the clear running water, the valve is closed by grasping the combined handle and spray head and turning the who stem to the right so as to seat the valve disk. it will here he noted that this last operation of closing the valve is done with clean hands, and the water issuing from the valve will he directed all around the head or handle, thereby cleansing the same and leaving it in a elean and sanitary roudition after each use thereof.

Having thus described what we claim is 1. A spray valve roniprising a easing having a. valve Stll, a rotatahle valve stem extending through the easing a. hollow spray head earried ('otn'entrieally on the outer end of the valve stem, said head having a series of perforationa therein. a valve disk on the inner end of the valve stem, said disk being arranged to engage the valve seat in closing the valve, said valve stem having an aperture eonneeting the interior of the casing with the interior of the. spray head and said spray head forming a handle for turning the valve stem to move the. valve disk toward and away from the valve seat.

2. A spray valve comprising at (using havin a valve seat, a rotatable valve stem exten ing through the casing, a hollow spray head carried tmieentrieally on the outer end of the valve stem, said head having a series of erforations in the wall thereof, a valve risk on the inner end o if the invention.

said valve stem, said disk being arranged to engage the valve seat in closing the valve, said valve stem having an aperture eonnertiug the interior of the -asing with the interior of the spray head and said spray head forming a handle for turning the valve stem to move the valve disk t0- ward and away from the valve seat and adinst ahle means within the sp'ay head for regulating the flow of fluid into the spray head.

3. A spray valve comprising a casing having a valve seat, a. rotatable valve stem extending through the casing and having a screw threaded eonnertion therewith, a hollow spray head rarried concentrically on the outer end oi the valve stem, said head having a plurality of perforations in the wall thereof, a valve disk on the inner end of said valve stem. said disk heing arranged to engage the valve seat in rlosing the valve. said valve stem having an aperture ronnerting the interior of the easing and hollow spray head and. said spray head forming a handle for turning the valve stem to move the valve disk toward and away l'roni the valve seat and adjustable means within the spray head for regulating the How of lluid into the spray head.

4. A spray valve comprising a easing having a valve seat, a. rotatable valve stem extending through the easing and having a screw threaded eonnertion therewith, a hol low spray head rarried concentrically on the outer end of the valve stem, said head having a plurality of perforations in the wall thereof. a valve disk on the inner end of said valve stem, said disk being arranged to engage the valve seat in closing the valve. said valve stem having an aperture eonnert ing the interior of the easing with the in terior of the spray head and said spray head forming a handle for turning the valve stem to move the valve disk toward and away from the valve seat.

5. A spray device for wash has-ins comprising a casing having an inlet port. a valve for the port, an axially rotatable valve stem for ('ontrolliug the valve. and a com hined handle and spray nov zle disposed eon eentrieally upon the outer end of, the valve stem, the stem having aconduit leading from the interior at the easing and dis eharging into the nozzle wherel'iy the acts of opening and closing the valve subjects the hand of the operator to the spray issuing from the nozzle while the hand is engaged with the nozzle.
